Oculus Go Companion Smartphone App

Hi,I have found that the oculus Go ecosystem is quite difficult for a lot of people to use. Is it possible to develop a companion smartphone app for my oculus app that can outsource some of the UI navigation, customization, etc. so that they can do everything on the mobile device and then just put the headset on to do an experience? Is this possible or has something similar been implemented? Does oculus have support for 3rd party smartphone apps to interact with the oculus backend and the oculus app?
